BLASTING-FUSE IGNIIER.

Specification of Letters Patent.

Patented March 10, 1908.

Application filed October 21, 1907. Serial No. 398,475.

T 0 all whom it may concern:

Be it known that I, BENJAMIN F. PEAR- soN, a citizen of the United States, residing at Canyonville, in the county of Douglas and State of Oregon, have invented certain new and useful Improvements in Blasting-Fuse Igniters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in blasting fuse igniters.

The object of the invention is to provide means whereby the end of a blasting fuse will be protected from dampness, and means whereby the same may be quickly and easily lighted.

With this object in view, the invention consists of certain novel features of construction, combination and arrangements of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side view of the end of a blasting fuse showing the application of the invention thereto; Fig. 2 is a longitudinal sectional view of the same; and Fig. 3 is a similar view showing the parts separated.

Referring more particularly to the drawings 1 denotes the fuse, which may be of the ordinary or any preferred construction. Adapted to be applied to the outer end of the fuse is a metallic cap or ferrule, 2, the outer open end of which is contracted or turned inwardly to a slight degree as shown at 8. In said outer open end of the cap is arranged a highly inflammable material which forms the igniter 4.

The igniting material 4 is'preferably constructed of raw cotton with which is combined a mixture of common gun powder to which is added a small percentage of giant powder. In preparing the igniting material, the gun powder and the giant powder are mixed together and moistened with water to form a pasty solution which is mixed with the cotton, after which the mass is rolled out in small rolls of slightly less diameter than the caps or ferrules, 2. After the igniting material has been thus rolled out it is permitted to dry and is then cut up into suitable lengths or pieces, one of which is placed in each of the caps or ferrules and rammed or tamped hard into the contracted end of the cap with a suitable tamping instrument. When the caps have thus been prepared they are in condition to be slipped upon the outer end of the fuse.

Then the caps have thus been applied to the fuse, the end of the latter will be prevented from becoming damp or injured and will be protected until ready for lighting, which is done by placing a lighted match or candle to theigniting material in the outer end of the cap, which quickly takes fire from the match or candle and forms a perfect igniting means for the fuse which never fails to be lighted by the burning of the igniting fuse.

By the use of my igniter, the necessity of splitting or fraying out of the end of the fuse is dispensed with and when used in connection with the fuse for blasting in wet or damp mines, the end of the fuse will be kept dry and in condition for quickly lighting at any time.

Having thus described my invention, what I claim as new, and desire to secure by Letters- Patent, is:

1. A fuse protector and igniter comprising a metal cap having areduced or contracted outer end and adapted to be applied to the outer end of the fuse and means in the outer end of said cap whereby the fuse may be quickly ignited, substantially as described.

2. A fuse igniting device comprising a cap or ferrule having a reduced or contracted open outer end and a wad of highly inflammable material packed in said outer end, substantially as described.

3. An igniting and protecting device for blasting fuses, comprising a ferrule or cap adapted to be applied to the outer end of a fuse, said cap or ferrule having a contracted or inwardly turned open outer end, an igniting wad arranged in said outer end of the ferrule, said wad consisting of a composition of raw cotton and powder adapted to be packed or rammed into the outer end of the cap, substantially as described. 4

4. An igniting material for fuses consisting of a composition of raw cotton, gun powder and giant powder constructed in the form of wads, and means to hold said wads in engagement with the end of the fuse, substantially as described.

5. A fuse igniter consisting of raw cotton mixed with gun powder having combined therewith asmall percentage of giant powder, such gun powder and giant powder being mixed with water to form a pasty solution which is thoroughly mixed with the cotton and formed into small rolls and dried, after which said rolls are cut into lengths or pieces to form igniting wads, and means whereby said wads are held in engagement with the end of the fuse, substantially as described.

6. A fuse igniter consisting of raw cotton mixed with gun powder having combined therewith a small percentage of giant powder, such gun powder and giant powder being mixed with water to form a pasty solution which is thoroughly mixed with the cotton and formed into small rolls and dried, after which said rolls are cut into lengths or pieces to form igniting wads, and a metallic cap or ferrule adapted to be applied to the end of a fuse to hold said igniting wad in engagement therewith, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

BENJAMIN F. PEARSON.
